Authentication error on Samsung tablet

Good evening,

You need to explain a bit better what’s happening to you... Normally, your seller should support you on this one... because there's a technical aspect involved, it's not just groceries..!

You mention authentication error and also password... So, which one is it..?? What do you want to connect to..?? Are you at home trying to connect to your BOX...?? Or is it a public access point, like at Leclerc or McDonald's for example..??

If your WiFi key is correct, you connect to the WiFi... That doesn’t mean you're connected to a webpage... especially if it's your neighbor's..

After successfully connecting to WiFi, you try to connect to Google for example... you could very well get a homepage from your hotel or the campsite's website, asking for the password to connect to the web... it's the site owner who gives you this password if you're one of the clients... whether it's Leclerc, McDonald's, the hotel, or the campsite...

If you don't have it, it won't work... there are no secrets.

Good evening, thank you for your response.
I want to connect to my box.
I get a message saying that my device is not connected to a Wi-Fi network.

I click on select a Wi-Fi network.
My box appears but underneath I have the message authentication error.

You must choose your BOX and no other... even if it is below..
If it connects to another one, it needs to be disconnected... to put your BOX first.
-- Provide the references of your BOX, the provider, and the model..??
-- You also need to cooperate if you want results.. instead of saying it doesn't work, you need to provide what is displayed on the screen... or take a clear photo and attach it here...

-- After selecting your BOX from the networks, you need to enter the Wifi key that belongs to your BOX.
Stand about a meter away from your BOX for this operation.

Then wait a bit for it to search and connect... I believe this process is explained in the manual... Since it's the same everywhere.
